Dr. Jonathan Losos, Department of Organismal and Evolutionary Biology, Harvard University, is a comparative biologist with a research focus on the behavioral and evolutionary ecology of lizards. Major questions concern how lizards interact with their environment and how lizard clades have diversified evolutionarily. His approach involves the integration of behavioral, ecological, functional morphological, and phylogenetic studies. A major focus has been the evolutionary radiation of Caribbean Anolis lizards, but other lizard radiations are also being studied.
